3 Claims.

This invention relates to a device for fastening receptacles, such as sink-strainers or the like, to sinks.

An object of the invention is to provide a simple, inexpensive device for removably clamping sink-strainers or the like to the rim of the usual kitchen sink, for example, so that the strainer will be firmly supported away from the bottom of the sink to permit free drainage of the strainer.

Other objects of the invention will be manifest from the following brief description and the accompanying drawing.

Of the accompanying drawing:

Figure 1 is a perspective view, partly broken away and in section, illustrating the use of the improved device for clamping a sink-strainer to the rim of one type of kitchen sink.

Figure 2 is a cross-section, partly broken away, taken substantially at line 2-2 of Figure 1.

Figure 3 is a view, partly broken away, taken from the left of Figure 2.

Figure 4 is a cross-section similar to Figure 2, on a reduced scale, illustrating an adaptation of the invention to another type of kitchen sink.

Referring in particular to Figures 1 to 3, the numeral designates generally a sink-strainer fastening or clamping device, comprising a single piece of spring steel wire bent substantially as shown, with a looped or U-shaped portion ll having a straight bottom cross-piece I2 for full contact with a flat inner surface of one side of a sink-strainer I3, of known type. The ends It and I5 of the wire may be bent outwardly substantially at right angles from the plane of the loop to provide substantially spaced, straight portions l4, l5, adapted to engage the rim I3 of strainer l3, for holding outwardly projecting portions of said rim against top inner edge portions of the rim iii of a. sink Iii, also of known type, and thereby to prevent the strainer from rocking, tilting or sliding down the side of the sink. The ends of the wire are bent from the straight portions I i l5, to conform to the curved outer portions of the rim l6 of the sink and then bent inwardly at M Hi", to hook under the outer edge of the sink rim I'B thereby to prevent lateral tilting of the clamping device It) on the rim of the sink. The end I! of the wire may have a downwardly and inwardly extending arm !8 provided with a straight portion l8 for yielding engagement with the outer face of the sink I6 at a point below the bottom of loop II to transmit yielding clamping pressure to the cross-piece l2 thereof engaging against the strainer I3.

bility of the device may be enhanced by forming one or more coils I9 in the arm l8 between the bend l5 and the straight portion I8.

In the use of the fastening device iii, the strainer I3 is first held with a flat face thereof against the inner face of the sink and with its rim l3 against top inner edge portions of the sink rim Ili as best shown in Figure 2. Next, the clamping device I0 is sprung over the rim Ili of the sink to engage the loop H against the inner face of the strainer, and to engage the spring arm l8 against the outside face of the sink, thereby applying clamping action yieldingly to urge the loop H against the strainer to retain the same in position on the sink. Engagement of the portions M [5 of the device with the top edge of the strainer maintains the rim |3 of the strainer against the top inner edge of the sink rim [6 to hold the strainer firmly against rocking, tilting, or downward sliding movement of the same when the strainer is loaded in use.

The improved fastening device makes it possible to clamp the sink-strainer firmly inposition in spaced relation to the bottom of the sink, thereby allowing the strainer to drain freely and obviating the usual objectionable dripping of liquid, for example, when the strainer is removed for emptying refuse therefrom.

The fastening device Ill shown in Figure 4 is similar to the device It] previously described, except that it is formed to clamp sink-strainer l3 in position on a sink 26 having flat rim portions 20 Like parts, therefore, are given like numerals. In a similar manner, the improved clamping device may be designed or adapted to clamp receptacles, such as sink-strainer it, onto kitchen sinks of a wide range of known shapes.

Modifications of the invention may be resorted to without departing from the spirit thereof or the scope of the appended claims.

What is claimed is:

1. A device for clamping a sink strainer or like receptacle to a sink, comprising a length of spring-like wire formed with a central loop, the ends of the loop extending upwardly substantially in a plane thereof, said ends having portions extending outwardly of said plane of the loop in substantially spaced relation and being bent downwardly, at least one of said downwardly bent portions being extended downwardly beyond the bottom of the loop and inwardly of said plane thereof.

2. A device for clamping a sink strainer or like receptacle to a sink, comprising a length of Yielding flexispring-like wire formed with a central loop, the

ends of the loop extending upwardly substantially in a plane thereof, said loop having a substantially straight portion extending transversely at the bottom thereof, said ends having portions extending outwardly of said plane of the loop in substantially spaced relation and being bent downwardly, at least one of said downwardly bent portions being extended downwardly beyond the bot tom of the loop and inwardly of said plane thereof.

3. A device for clamping a sink strainer or like receptacle to a sink, comprising a length of spring-like wire formed with aqcentral loop, the

ends of the loop extending upwardly substantially in a plane thereof, said loop having a substantially straight portion extending transversely at the bottom thereof, said ends having portions extending outwardly substantially at right angles to said plane of the loop in substantially spaced relation and being bent downwardly to provide hook-like portions, at least one of said downwardly bent portions being extended downwardly beyond the bottom of the loop and inwardly of said plane thereof.
